This is a great find. This is a new in the package set of rings for the  1973 1974 1975 CB125 and CL125 Scrambler which were the  single cylinder, four-stroke Hondas. Also correct for the 1971 1972 1973 1974 SL125 model.  This is a standard size ring set and is replacement for part # 13011-324-014 and 13011-330-005. This has the 2 compression rings and the lower 3pc oil control ring, everything to get your piston compression back where it should be.   Get your old bike up and running again. We only sell the best! This is a top-quality aftermarket item. Good stuff if you are riding or restoring.
